2-Butene-1,4-diol Usage And Synthesis
Description2-Buten-1,4-diol is a palladium-containing compound that forms cross-links by reacting with an oxygen nucleophile. It reacts with nitrogen nucleophiles in the presence of hydrochloric acid to provide gamma-aminobutyric acid. This reaction mechanism is analogous to the way in which amines react with carboxylic acids to form amides. cis,trans-2-Buten-1,4-diol can be found in kinetic studies and its nmr spectra have been studied extensively.
Chemical PropertiesColorless to light yellow liquid
UsesIt is used to make agricultural chemicalsand the pesticide endosulfan; and as anintermediate for making vitamin B.
Application2-Butene-1,4-diol has been used as a cross-linking agent for various polymers and is also able to form hydroxyl groups through allylation reactions.
Reactivity Profile2-Butene-1,4-diol forms furan (narcotic)when treated with dichromate in acidic solution.Dehydration of the cis-isomer overacid catalysts yields 2,5-dihydrofuran (narcotic).Halogens form substitution or additionproducts, 4-halobutenols, or 2,3-dihalo-1,4-butanediol. These are toxic compounds.Ammonia or amine form pyrroline or itsderivatives (moderately toxic).
Health Hazard2-Butene-1,4-diol is a depressant of the Centralnervous system. Inhalation toxicity isvery low due to its low vapor pressure. Theoral LD50 value in rats and guinea pigs is1.25 mL/kg. It is a primary skin irritant.
Fire HazardNoncombustible liquid; flash point (open cup) 128°C.
